[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0021] Figure 1-Figure 3 The schematic diagram of the whole structure of the oil field pipeline booster device of the utility model is shown in FIG. Figure 1-Figure 3The present embodiment is a kind of oil field pipeline boosting device, including a main pump station 100, the main pump station 100 has an oil inlet pipeline 110 connected to the oil source at the oil inlet end and an oil outlet pipeline 120 for remote transmission at the oil outlet end, a plurality of pressure sensors 500 are arranged near the main pump station 100 and along the length direction of the oil inlet pipeline 110, and the main pump station 100 is also matched with an oil storage tank 200, an oil guide pipeline 300 is connected to the oil outlet pipeline 120 and the other end is connected to the oil storage tank 200, and the oil guide pipeline 300 is provided A flow pump 310 is provided, and an oil delivery compensation sleeve 460 is provided on the oil inlet pipeline 110 and near the oil inlet end of the main pump station 100. One side of the oil delivery compensation sleeve 460 is connected to a dosing pipeline 400 and the other end is connected to the oil storage tank 200. A diaphragm metering pump 410 is provided on the dosing pipeline 400. The oil field transmission pipeline boosting device is centrally managed by a control center to coordinate boosting compensation, and a plurality of on-off valve devices are also provided on the oil guide pipeline 300 and the dosing pipeline 400.
[0022] An electromagnetic flow valve 320 is also provided on the oil guide pipeline 300 and adjacent to the oil outlet pipeline 120, and a stop valve 330 is provided on the oil guide pipeline 300 and adjacent to the oil storage tank 200. During use, when the main pump station 100 cooperates with the normal operation of the inlet and outlet oil pipelines, and when the oil storage tank 200 needs to be supplemented with oil, the control unit will open the electromagnetic flow valve 320, the flow pump 310 and the stop valve 330 at the same time. The specific operation is that the electromagnetic flow valve 320 will control and reduce its conduction opening, and the flow pump 310 will slowly suck the oil in the runoff oil outlet pipeline 120 through the oil guide pipeline 300 to prevent the smooth delivery and pressure stability of the oil outlet pipeline 120 from being affected by excessive unit suction volume. When the oil in the oil storage tank 200 is filled to the calibrated liquid level, the system will close the electromagnetic flow valve 320, the flow pump 310 and the stop valve 330.
[0023] A stop valve 2 440 is provided on the dosing pipeline 400 and is adjacent to the oil storage tank 200, and a stop valve 3 450 is provided on the dosing pipeline 400 and is adjacent to the oil delivery compensation pipe sleeve 460.

A flow calibration column 430 is also provided on the dosing pipeline 400 and is located in the middle area between the oil inlet end of the diaphragm metering pump 410 and the stop valve 2 440. Here, the flow calibration column 430 is used to measure the pressure change of the oil in the calibration column and calculate the unit flow rate. The system will compare the data with the reading of the diaphragm metering pump 410, thereby determining the error and calibration coefficient of the metering pump, and ensuring the stable output of the metering pump. A diaphragm pressure gauge 420 is provided on the dosing pipeline 400 and adjacent to the stop valve 440, and the diaphragm pressure gauge 420 is located in the oil outlet direction of the diaphragm metering pump 410.

The control system can interactively analyze and compare various data such as the flow calibration column 430 and the diaphragm pressure gauge 420, so as to finely control the unit output of the metering pump, the compensation dosage of oil and the dosage time. In this embodiment, by arranging a plurality of pressure sensors 500 on the oil inlet pipeline 110, the plurality of pressure sensors 500 can perform interval detection on the internal pressures of different sections of the pipeline, and the control unit will generate a pressure curve diagram of the oil pipeline according to the different pressure values of the pipeline, so as to analyze and determine the oil boost compensation required for the oil inlet pipeline 110 when it is about to enter the main pump station 100, and then control the output volume and output time of the dosing pipeline 400, thereby effectively avoiding the problem of sudden changes in output pressure of the oil pipeline due to unstable unit output volume, which in turn causes bad pulsation in the pipeline, reduces the stroke load of the pump, and provides good protection for pipeline operation and hardware matching.
[0024] The oil inlet pipelines 110 at both ends of the oil delivery compensation sleeve 460 are connected, and the axial part of the oil delivery compensation sleeve 460 has a central cavity 4601 which is bidirectionally through and linearly connected to the oil inlet pipeline 110, and the inner part of the oil delivery compensation sleeve 460 has an annular oil cavity 4602, and the inner side wall of the central cavity 4601 is circumferentially provided with a number of evenly distributed oil delivery holes 4603 which are connected to the annular oil cavity 4602. When performing oil pressure boost compensation, when the oil in the dosing pipeline 400 is injected into the annular oil cavity 4602, under the action of pressure, the oil will be rapidly distributed to the peripheral side of the central cavity 4601 through the oil delivery holes 4603, thereby avoiding adverse disturbances to the oil in the main pipeline, and ensuring the linear compensation and stable operation of the oil pipeline.
[0025] In summary, in an oilfield pipeline boosting device according to the present embodiment, when in operation, the diaphragm pressure gauge 420 will perform real-time detection of the unit output pressure of the dosing pipeline 400, and the control system can interactively analyze and compare various data such as the flow calibration column 430 and the diaphragm pressure gauge 420, so as to finely control the unit output of the metering pump, the compensation dosage of oil and the dosage time, and by arranging multiple pressure sensors 500 on the oil inlet pipeline 110, the multiple pressure sensors 500 can perform interval detection of the internal pressure of different sections of the pipeline, and the control unit will generate a pressure curve diagram of the oil pipeline according to different pressure values of the pipeline, so as to analyze and determine the oil boost compensation required for the oil inlet pipeline 110 when it is about to enter the main pumping station 100, and then control the output volume, output time, etc. of the dosing pipeline 400, effectively avoiding the problem of sudden changes in output pressure of the oil pipeline due to unstable unit output, which in turn causes bad pulsation in the pipeline.
